To all whom it may concern: 1

Beit known, that I, FENTON ToiuLmsoN, citizen of the United States,residing at San Diego, in the county of'San Diego and State ofCalifornia, have. invented certain new and useful Improvements inDriving and Releasing Mechanism, of which the followin is aspecification.

y invention relates to mechanical move- 10 ments and particularly tomeans for driving a driven element from a driving-element and at willreleasing the driven element from the driving element.

a "simple andreliable rotary driving mecha- A further object is toprovide means.

whereby the forces acting on the driving element to get reverse motioncan either be applied dlrectly to the driving element 'or' ap lieddirectly to the'driven element. y mechanical movement is shown in theaccompanying drawings, itbeing understood that the movement maybeapplied-to .a large variety of mechanism.

driven element of said m'echanism from a a driving element.

In the embodiment of my invention which is illustrated in the drawings,2 designates a central" shaft which is supported in any suitable mannerand which is surrounded .by'a, tubular rotatable shaft 3 which forms--the driving shaft, this rotatable shaft 3 being driven in any suitablemanner and being provided with the rotatable driving element 4:, whichin the illustration of my invention has the form of a'disk. It is to be.understood that while I have shown the-disk 4 as being mo'untedupon anddriven with the tubular shaft 3, the disk 4 might be driven in anysuitable manner and rest directly upon the shaft 2. Located immedi- 7oately ad acent to the disk 4, as for instance upon the shaft 2, is arotatable driven element 5 which in this embodiment of my inventionhas'the form of a disk, which disk is provided upon its circumferencewith ratchet teeth 6; 1

- Located immediately adjacent tothe disk '5 and in fixed relation tothe driving and driven members 4 and 5, is a fixed element 7 also havingthe form of a disk. and shown as mounted upon the shaft 2 butnon-rotatable therewith. In the illustration I this disk 'I is sup ortedby means of a bracket 8 which exten s upward from a base 9 supi portedin any suitable manner. I'do not wish to limit myself, however, to anyparticular means for supporting the disk 7 fixedly with relation to thedriving and.

driven elements.

ing element 4 to t e driven-element 5, I mount uplon the inner face ofthe driving element t e pawl 10. This is pivoted at its outer end as at11 adjacent to the circumference of the disk and it's free end isangularly bent and adapted toengage with the p ratchet teeth 6. A spring12'may be used to forcethe free .end of the pawl 10 into engagement withthe ratchet teeth 6 and a stop 13 may be used to limit the outwardmovement of the pawl. I do not, however,

wish to limit myself to these features. Pivotally mounted upon the pawl10 is u,

pawl14 which is oppositely directed with relation to the pawl 10and'which "ngages with relatively short ratch-et teeth 15 formed heunnecessary wear and jar. By using the catch 29, the pawl is held out ofengagement when once thrown. The catch may he tripped with the finger,21 will return to its usual position.

What I claim is: d
